In an age of detrimental climate change, urban cultivation and green roof agriculture will soon be necessary as food, water and energy resources become scarcer.

New York City black tar roofs cause a number of environmental problems, including air pollution, heat absorption that raises energy consumption, and storm water runoff in the sewer system.

New York City has a pilot program offering financial help for green roofs.

In Louisville, KY, many people suffer from allergies or asthma and need to take inhalers to assist their breathing. A new inhaler called Propeller Health connects to Bluetooth devices to help patients track their inhaler dosages as a form of self-surveillance. The data collected also has a broader impact, offering scientists insight on people’s breathing patterns in different geographic regions as well as the effectiveness of certain medicated inhalers.

Urban areas contain the highest in concentration of burning fossil fuels, which negatively contributes to climate change. Spearheading the green energy movement, Burlington, VT claims that its city uses 100% renewable energy for electricity. Burlington’s efforts pilot a model for larger U.S. cities to follow.
